*SAMIfalt
Chemically Modified Polymer Binders for use in Asphalt Concrete Mixes
SAMIfalt binders are used as an alternative to C170 or C320 bitumen in the manufacture of asphaltic concrete. SAMI Bitumen Technologies manufactures this range of binders in a purpose built manufacturing plant that includes facilities for thermodynamic, mechanical treatment and chemical modification. The binder is supplied to the asphalt producer for the manufacture of asphaltic concrete which is required to have increased performance levels to that of asphalt incorporating standard grade bitumens.
Features and benefits
SAMIfalt offers the engineer the advantage of an A.C. mix with vastly improved mechanical and other properties in terms of service and performance over conventional A.C. mixes. These include improvements in:
- Resistance to permanent deformation and creep deformation (shoving and rutting)
- Fatigue behaviour (relationship between tensile strain and number of load applications to failure) ie. improved crack resistance
- Tensile strength and elastic modulus
- Resistance to crack propagation (reflective cracking)
- Temperature susceptibility (improved performance in higher and lower temperature regions/extremes)
- Stripping resistance
